Example 1
Referring to fig. 1, 2 and 3, the main body of the present embodiment is a smoke evacuation system for laparoscopic surgery, which includes a smoke evacuation filtering structure for laparoscopic surgery, and further includes a suction rod 4, a suction tube 5 and a vacuum source 6 connected in sequence, wherein an exhaust end of the smoke evacuation tube 1 is connected between two ends of the suction tube 5.
In this embodiment, the smoke exhausting and filtering structure for laparoscopic surgery includes:
the smoke exhaust pipe 1 is provided with an air inlet end and an air outlet end, the air inlet end of the smoke exhaust pipe 1 is communicated with the air outlet pipe 21 of the puncture outfit sleeve 2, the air outlet end of the smoke exhaust pipe 1 is communicated with the vacuum source 6, and a filter pipe 3 is arranged between the air inlet end of the smoke exhaust pipe 1 and the air outlet pipe 21 of the puncture outfit sleeve 2;
two ends of the filter pipe 3 are respectively provided with a connecting structure for detachably connecting with the air inlet end of the smoke exhaust pipe 1 and the exhaust pipe 21 of the puncture outfit sleeve 2;
the connecting structure comprises an annular contact tooth 31 and an annular spring 32;
the annular contact teeth 31 are arranged on the inner edge of the end part of the filter pipe 3 and are used for contacting the outer edges of the smoke exhaust pipe 1 and the exhaust pipe 21 to form circumferential sealing; the annular spring 32 is sleeved on the end part of the filter pipe 3 and applies radial compensation force to the annular contact teeth 31 to enable the annular contact teeth to be in interference contact with the outer edges of the smoke exhaust pipe 1 and the exhaust pipe 21.
During the operation, when smoke is present in the abdominal cavity of the patient, the practitioner can open the exhaust tube 21 of the puncture device sleeve 2. At this time, the vacuum source 6 (in this embodiment, a negative pressure pipeline of a hospital) extracts the smoke exhaust pipe 1 connected to the suction pipe 5, so that the smoke is caused to sequentially pass through the filter pipe 3, the smoke exhaust pipe 1 and the suction pipe 5 and enter the negative pressure pipeline, thereby preventing the smoke from being accumulated inside the abdominal cavity of the patient.
In the present embodiment, the annular contact teeth 31 are mainly used to contact the ends of the filter tubes 3 with an interference fit, thereby forming a circumferential seal. When the device is installed, an implementer only needs to plug the exhaust pipe 21 and the smoke exhaust pipe 1 of the puncture outfit sleeve 2 into the two ends of the filter pipe 3 by force, so that the annular contact teeth 31 are matched with the exhaust pipe 21 and the smoke exhaust pipe 1 of the puncture outfit sleeve to generate elastic deformation, and circumferential sealing can be realized. Meanwhile, the annular spring 32 is sleeved outside the end part of the filter pipe 3, so that the annular spring always provides a deformation force for the annular contact tooth 31, and the contact tightness between the annular contact tooth 31 and the exhaust pipe 21 and the smoke exhaust pipe 1 of the puncture outfit sleeve 2 is guaranteed. Correspondingly, when the device is disassembled, the operations are performed reversely.
The laparoscopic surgery filtration that discharges fume that this embodiment provided has optimized the connection structure who has improved filter tube 3 both ends department for medical staff can install fast/disassemble filter tube 3 down, conveniently maintains.
In the present embodiment, the filter tube 3 is filled with activated carbon 34 for absorbing smoke, specifically, in the present embodiment, two partition nets 33 are sequentially arranged in the filter tube 3 along the axial direction thereof at intervals, and the space between the two partition nets 33 forms a filling space for filling the activated carbon 34.
As activated carbon 34 in filter tube 3 primarily absorbs smoke particles, it blocks the area of filter tube 3 near exhaust tube 21 of piercer sleeve 2 over time, which may lead to blockage of filter tube 3 early in use.
Therefore, as a preferred embodiment, in the present embodiment, along the axial direction of the filtering pipe 3, the inner diameter of the inner cavity of the filtering pipe 3 gradually increases and then gradually decreases, one of the two separation nets 33 is disposed at the maximum inner diameter of the filtering pipe 3, and the other is disposed at the minimum inner diameter of the filtering pipe 3; the separation net 33 arranged at the position with the largest inner diameter of the filter pipe 3 and the separation net 33 arranged at the position with the smallest inner diameter of the filter pipe 3 are sequentially arranged along the direction from the puncture outfit sleeve 2 to the smoke exhaust pipe 1. The arrangement mode can increase the contact area of the activated carbon 34 close to the front side of the exhaust pipe 21 of the puncture outfit sleeve 2 and smoke, prevent the activated carbon from being failed in the early stage of use, and improve the service life of the whole activated carbon 34.
Meanwhile, as a preferred embodiment, in this embodiment, the connection structure further includes a fitting groove 35 concavely formed on an outer edge of the end of the filter pipe 3, the fitting groove 35 being used for fitting the ring spring 32 to prevent the ring spring 32 from being detached from the filter pipe 3.
In addition, as mentioned above, when installing, the operator only needs to force the exhaust pipe 21 and the smoke exhaust pipe 1 of the puncture outfit sleeve 2 to plug into the two ends of the filtering pipe 3, and then the installation can be completed. In order to prevent the exhaust pipe 21 or the smoke exhaust pipe 1 from damaging the separation net 33 in the filter pipe 3, in this embodiment, the filter pipe 3 is further provided with two limiting structures for contacting with the end portions of the smoke exhaust pipe 1 and the exhaust pipe 21 of the puncture outfit sleeve 2, the two separation nets 33 are arranged between the two limiting structures, and the limiting structures are mainly formed by limiting blocks convexly formed on the inner edge of the filter pipe 3. The limiting blocks are mainly used for abutting against the end faces of the exhaust pipe 21 and the smoke exhaust pipe 1 and preventing the end portions of the exhaust pipe 21 and the smoke exhaust pipe 1 from puncturing the separation net 33.
In the present embodiment, the smoke exhaust pipe 1 is further provided with a flow rate regulating valve (not shown) for intercepting or regulating the flow rate of the smoke exhaust.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
